Bad Link Checker and Child Theme Questions

The title pretty much says what I want to ask:

1. Does this plugin come with a way to check for and “disable” bad links, 404, redirects, etc?

2. When using the Directory “default” theme, does it support the use of a Child Theme (for the “default” theme)? In this way, we can always avoid theme customizations being overwritten during an upgrade.

Thanks.
